Top 100 Manufacturers 2018 Report

Window & Door’s annual Top 100 Manufacturers list details North America’s 100 largest manufacturers of residential windows, doors, skylights and related products, based on sales volume. Top 100 sales dataMuch of the information comes from companies directly, which our research team verifies and fact-checks. We also rely on this research to fill in the blanks of those that do not participate in our survey. While our annual Industry Pulse survey looks at the industry as a whole (information published in the January/February issue), the information published here provides stats specifically regarding companies on our Top 100 List. It is important to note, however, that the overarching theme of the Industry Pulse echoes the sentiments of this report: the industry is healthy, moving in a direction of growth. 


While the industry has seen much consolidation in the past decade, the Top 100 Manufacturers haven’t changed drastically in the past five years. Though we saw some major brands pick up other manufacturers to diversify offerings, simplify distribution and/or strengthen market share, the acquired companies weren’t, in most cases, on previous Top 100 lists.

Here is a quick recap of that M&A activity involving our Top 100 Manufacturers from 2017: 

  • Jeld-Wen purchased MMI Door in the U.S.; as well as international companies the Kolder Group in Australia and Domoferm in Austria 
  • Pella acquired Bonelli Windows & Doors 
  • Masonite acquired A&F Wood Products 
  • Dunes Point Capital added on to portfolio company Harvey Industries with Soft-Lite at the end of 2016; Harvey Building Products acquired Thermo-Tech in March of 2018 (reflected in this year’s list)

Top 100 sales data2018 has already seen some notable acquisitions involving Masonite, Andersen, Ply Gem and Jeld-Wen, to be noted in next year’s Top 100 List. 

Looking from year to year, it is also evident that business is looking good for our Top 100. We’ve seen downward movement in the past, but saw companies generally moving up our sales categories this year. Just one of the Top 100 Manufacturers that completed our survey reported that sales in 2017 were lower than in 2016. 

As stated in our annual Industry Pulse article published earlier this year and confirmed by the select group of manufacturers listed here,
vinyl continues to dominate the offerings on the market. Our estimate is that about three quarters of the manufacturers on the list are primarily manufacturing vinyl goods. In terms of the door manufacturers on the market, the majority are producing fiberglass, but steel and wood both maintain healthy market share, especially in the high-end space.  

We asked those on our Top 100 list about their trials in 2017 and the answer is not surprising: recruiting, hiring and training the workforce remains the biggest challenge. Keeping up with customer and market demands is another struggle related to the labor issue, as well as managing growth, maintaining efficiency and contending with rising material costs. 

Top 100 dataDespite ongoing labor issues, our Top 100 Manufacturers are employing tens of thousands of workers. The majority of the companies in our top five categories (sales between $100 million and over $1 billion) employ between 1,000 and 2,000 workers. The highest of those that reported employment statistics was 5,600 employees; the lowest number of employees reported is 50.
